PHP2Shell: What Actually Protects You Before the 14:00 UTC PHP RCE Patch, and What Doesn't

A security firm has clarified that a previously suggested setting is insufficient to protect against the PHP2Shell vulnerabilities on its own. PHP is set to release a patch for the two critical flaws, rated 9.2 out of 10, at 14:00 UTC. The patch will address the vulnerabilities, but until it is installed, certain measures may lower the risk. However, a specific setting being circulated as a workaround is not enough to fully block the flaws. The security firm initially suggested this setting, but now notes its limitations. PHP has not provided an official workaround for the vulnerabilities prior to the patch release.
